  • Helium Neon Lasers-Image
    Helium Neon Lasers - (36 companies)
    Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation...
